[NTG-context] Contractions in ligature suppression word list

[denis.maier at unibe.ch]

A somewhat more complete testfile with a couple of options is below. My context installation is not current so please double check, but I think it boils down to this:  apostrophes seem not to be considered to be part of a word. Once I enable wolfin under \startlanguageoptions[en] it will disable the fi-ligature everywhere below, but adding the word variants with an apostroph doesn’t do anything, neither to the explicit wordlist under startlanguageoptions, nor in one of the additional goodies files.

Here's a short example (version 2022.05.11 11:36):

\setuplanguage[en][goodies={lang-en.llg}]

\starttext
  % Expected: no ligature; actual: as expected
  wolfish

  % Expected: no ligatures; actual: ligature
  wolfing
  wolfin'
  wolfin’
\stoptext


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\startluacode
-- Testfile for fi ligature over suffix boundary

local testoversuffixboundary = {
  name    = "test-over-suffix-boundary",
  options = {
    {
    patterns = {fi  = "f|i",},
    words = [[ wolf ]],
                suffixes = [[
    in'
                in’
                ]],
    },
  },
}

-- Testfile for fi ligature in word with apostroph
local testwithsuffix = {
  name    = "test-with-suffix",
  options = {
    {
    patterns = {fi  = "f|i",},
    words = [[ wolfin' wolfin’ ]],
    },
  },
}

-- which table do we want to test?
-- table.save("test.llg",testoversuffixboundary)
table.save("test",testwithsuffix)
\stopluacode

\setuplanguage[en][goodies={lang-en.llg,test.llg}]

% explicit suppression
\startlanguageoptions[en]
wolf|in' % this here doesn't do anything
wolf|in’ % this here doesn't do anything either
%wolf|in % this here disables the fi ligature across the board for all the words below
\stoplanguageoptions


\mainlanguage[en]

\starttext

% defined in lang-en.llg => works
   wolfish
   wolfing

  % Expected: no ligatures; actual: ligature
  wolfin'
  wolfin’

  % shibboleth
  wolfin

\stoptext
